Erich Gamma started VS Code (through Monaco). That's saying a lot about Erich Gamma and not a lot about Electron.

It's also had a ton of work done to make it performant. (Microsoft level resources)

Isn't Gamma one of the GoF guys who pushed bloated Design Patterns, UML & co? I would never expect him to write performant code.

Also, first time I'm hearing about Monaco. I thought VSCode was an Atom fork.
